EP1K50TI144-2Q 개요
An FPGA is a semiconductor integrated circuit that can be electrically reconfigured after manufacturing to implement arbitrary digital logic, ranging from simple glue logic to complete processor subsystems. The ACEX-1K family specifically uses a 2.5 V core (per the digchip datasheet synopsis), an Enhanced Embedded Array Block (EAB) architecture for on-chip SRAM, and dual-port RAM capability, bridging low-cost SRAM-based PLDs and high-density SRAM FPGAs. Within the broader taxonomy, an FPGA belongs to programmable logic devices -> logic ICs -> integrated circuits, alongside CPLDs and mask-programmed gate arrays.
Key features for this part include 102 user I/O pins (per DigiKey), 2,880 logic cells, 40,960 bits of embedded memory, in-system programmability via SRAM configuration cells, and built-in support for JTAG (IEEE 1149.1) boundary-scan testing. The 144-pin TQFP package offers a thin (1.0 mm) profile compatible with standard surface-mount assembly and provides a per-pin ESD protection structure typical of Altera ACEX-1K devices. Industrial temperature operation (-40 °C to +100 °C for the "I" grade) makes this part suitable for factory, outdoor, and automotive cabin environments.
From an architectural perspective, the ACEX-1K family combines Look-up Table (LUT)-based logic elements for combinatorial and registered logic with dedicated EAB blocks for efficient memory implementation. Each EAB can be configured as 4,096 bits of RAM (single- or dual-port) or as a wide logic function, allowing megafunctions such as FIFOs, dual-port RAMs, and CAMs to be mapped efficiently. Configuration bitstream is loaded from a serial or parallel PROM at power-up; the device retains its SRAM configuration as long as VCCINT remains within specification.
Typical applications for the EP1K50TI144-2Q include industrial control and factory-automation controllers, telecom line-card glue logic and protocol bridges, low-volume prototyping for ASIC designs, embedded DSP front-ends, and PCI/memory interface bridging. The 50K-gate density is sufficient for multi-channel UART/SPI controllers, motor-control state machines, and small RISC soft-cores such as the Altera Nios or open-source RISC-V implementations.
A key design consideration for ACEX-1K devices is power-supply sequencing: the 2.5 V VCCINT and VCCIO banks must ramp monotonically with VCCINT preceding VCCIO, otherwise in-rush currents through I/O structures can latch-up. The FPGA also requires a configuration source (EPCS or compatible serial flash) unless pre-loaded at the factory. Designers migrating from the ACEX-1K family should be aware that this is a mature device: it has been NRND or EOL at Intel for many years, so lifecycle planning and last-time-buy evaluation are recommended.

일반적인 애플리케이션
EP1K50TI144-2Q 적합 용도: 6 애플리케이션s: Industrial Control and Factory Automation, Telecom Line-Card Glue Logic and Protocol Bridging, ASIC Prototyping and Low-Volume Production, Embedded DSP and Signal Pre-Processing Front-Ends, PCI / Memory Interface Bridging, Legacy Test & Measurement Instrumentation.
Industrial Control and Factory Automation
The EP1K50TI144-2Q fits factory automation because its 2,880 logic elements, 102 user I/O pins, and industrial-temperature TQFP-144 package meet PLC, motor-controller, and protocol-bridge requirements. The 2.5 V core and JTAG boundary-scan simplify integration into backplanes that already host 3.3 V logic. Designers typically place the FPGA between sensor front-ends and an MCU, using EAB RAM for deterministic state-machine tables and the 50K-gate budget for PID loops, encoder counters, and EtherCAT/Ethernet/IP slave bridges. Compared with a microcontroller-only solution, this part improves parallel I/O throughput and deterministic latency for factory automation.
추천
Telecom Line-Card Glue Logic and Protocol Bridging
The EP1K50TI144-2Q serves telecom line cards well because its 102 I/O pins are sufficient for multi-protocol bridging (UART, SPI, I2C, HDLC, parallel TDM) while the 50K-gate budget absorbs framing and timing-recovery logic. The TQFP-144 footprint suits front-cards with tight board area, and the industrial temperature grade handles outdoor cabinet deployments. Designers use the dual-port EABs for elastic FIFOs between backplane clocks and serial streams, reducing latency for protocol conversion. Compared with discrete logic, this FPGA replaces 5 to 10 PAL/GAL devices with a single re-programmable part, lowering BOM cost and PCB area.
추천
ASIC Prototyping and Low-Volume Production
The EP1K50TI144-2Q is widely used as an ASIC prototyping platform because its 2,880 logic elements and 40,960 bits of EAB RAM support representative sub-systems at full speed. Quartus synthesis accepts Verilog and VHDL directly, and the 144-TQFP package offers sufficient I/O for real-world interfaces during bring-up. Low-volume production runs benefit because the FPGA eliminates NRE charges and mask costs compared with an ASIC spin, at the trade-off of higher per-unit device cost. Compared with discrete 74-series prototyping, this part accelerates verification by 5x-10x and reduces board complexity.
추천
Embedded DSP and Signal Pre-Processing Front-Ends
The EP1K50TI144-2Q works as an embedded DSP front-end because its 50K-gate budget implements FIR/IIR filters, FFT pre-processors, and digital down-converters ahead of a host DSP or MCU. The 40,960 bits of EAB RAM provide coefficient storage and sample buffering with predictable timing, while the 102 I/O pins accept parallel ADC data from audio or vibration front-ends. Industrial temperature operation suits outdoor and vehicular sensor conditioning. Compared with software DSP on a microcontroller, this FPGA delivers 10x-100x the throughput for parallel MAC operations, freeing the host processor for application-layer tasks.
추천
PCI / Memory Interface Bridging
The EP1K50TI144-2Q bridges PCI, ISA, and legacy memory buses because its 2.5 V core and 3.3 V-tolerant I/O banks support classic 33 MHz PCI signaling, while the 102 I/O pins are sufficient for 32-bit data, address, and control signals. The TQFP-144 footprint bridges legacy ASICs that have no modern replacement, extending equipment life in industrial test racks. Designers instantiate a PCI target core in the FPGA, leaving the legacy bus on one side and a modern Ethernet/UART bridge on the other. Compared with a discrete bus-translator chip, this FPGA adds flexibility, allowing post-deployment logic fixes via JTAG.
추천
Legacy Test & Measurement Instrumentation
The EP1K50TI144-2Q is well suited to legacy test-and-measurement platforms because its 50K gates and 102 I/O pins implement custom stimulus generators, pattern recognizers, and timing analyzers. Industrial temperature operation supports factory-floor and outdoor RF/antenna test stands. Engineers instantiate counter chains, sequencers, and pattern detectors in the FPGA while keeping the analog front-end and host CPU external. Compared with discrete TTL instrumentation designs, this FPGA reduces component count by 50%-70% and provides JTAG-based in-system debug, accelerating both development and field service.

설계 노트
The EP1K50TI144-2Q requires a 2.5 V core supply (VCCINT) and one or more VCCIO bank supplies. Estimated: with all 102 I/O toggling at 33 MHz and 50% density, expect 200-400 mA on VCCINT; add 0.5-1 A on VCCIO if driving heavy 3.3 V loads. Use a low-ESR bulk cap (>= 47 uF) plus 0.1 uF / 1 uF ceramic decoupling on each VCCINT and VCCIO pin. Sequence VCCINT before VCCIO at power-up to avoid I/O latch-up; allow VCCINT to lead VCCIO by >= 100 us.
TQFP-144 has a 0.5 mm pitch and 20 mm x 20 mm body; keep-out distance for traces is 0.2 mm minimum with 0.1 mm trace/space preferred for escape routing. Place the configuration PROM (EPCS1/EPCS4) within 25 mm of the FPGA DATA, DCLK, and nCONFIG pins, and add 33 ohm series resistors on DATA and DCLK if the distance exceeds 50 mm. Provide a clean, low-inductance GND return path under the package, using a continuous ground plane on layer 2.
Estimated: ACEX-1K SRAM configuration is volatile. The FPGA loses its configuration if VCCINT drops below 1.7 V for any length of time; use a supervisor with a 1.8 V threshold to assert nCONFIG low and trigger a reconfiguration. Do not leave JTAG TMS floating during normal operation - tie to VCCIO through 10 kohm to avoid accidental boundary-scan entry. Verify that your design does not exceed 50K typical gates when mapped to LEs (utilization typically reaches 90% of LEs, not gates).
